IMPROVEMENT IN GRATES FOR STOVES.`

Specification forming part of Letters Patent No. 161.790, dated April 6,1875 application led March 4, 1875.

T0 all whom it may concern:

Be it known that I, AMBROSE N. HOUSSE, of the city, county, and State ofNew York, have invented a certain new and useful Improvement in Stoves,ot' which the followingis a specification:

This invention is illustrated in the accompanying drawing, in Which-Figure 1 represents a vertical section in the plane x fr, Fig. 2, andlooking in the direction of the arrow opposite to that line. Fig. 2 is avertical section in the plane y y, Fig. 1. Fig. 3 is a detachedelevation of the lifting mechanism in a inodied form. Fig. 4 is ahorizontal section of the same in the plane z z, Fig. 3.

Similar letters indicate correspondingparts.

This invention relates to that class ofgrates for stoves which areprovided with a mechanism for raising or'lowering the same, in order tobring it nearer to or farther from the top plate of the stove, in orderto regulate the heat and the consumption of fuel.

My invention consists in the combination, with a grate provided with araising` and lowerin g mechanism, of a traverse secured to the liftingmechanism, and carrying the said grate, whereby the grate can be turnedto dump the tire, whatever the elevation of the grate may be, as willhereinafter be described in detail.

In the drawing, the letter A designates an ordinary cooking-stove, thegrate B of which is supported by a traverse, C. The ends of thistraverse are supported by rack-bars D, which are fitted in guide-boxesE, secured to the sides of the ash-chamber F of the stove. In theseguide-boxes are contained pinions G, which are mounted on shafts H andgear into the rack-bars D. The shafts El extend through the sides of thestove, and on their outer ends are secured cranks I, by means of whichsaid shafts can be turned. By turning the shafts H, or either of them,in the proper direction, the rack-bars D are moved upward, and the gratecan be adjusted at any desired elevation. Instead of rack bars andpinions, any other suitable lifting mechanism can be employed forelevating the grate, such, for instance, as screws Dit. (See Figs. 3 and4.) These screws extend through the bottom ot' the ash-chamber, and theyare turned by suitable hand wheels or cranks. They act on slides DO, towhich is secured the traverse G that carries the grate B. Said grate isfastened to the traverse by one or more set-screws, c, and the traverseis round, so that, by releasing the setscrews, the grate can be turnedand the lire dumped Without difficulty.

The advantages ot' this class of inventions consist in the fact that, byraising or lowering the grate, the lire can be brought closer to orfarther from the article to be heated. lf it is desired to heat a vesselsupported in the top plate of the stove with the least possible amountof fuel, the grate is raised. and by kindling a wood ire on the gratethe vessel can be heated very quick, and at the saine time the stove isbutl slightly heated. When it is desirable to heat the stove the grateis lowered.

Vhat I claim as new, and desire to secure by Letters Patent, is-

The combination, with a stove-grate pros vided with mechanism forraising and lowering the same, of a traverse connected` at its ends withthe said raising and lowering mechanism, and carrying the grate which isjournaled thereon, substantially as described, whereby the grate can beturned to dump the contents, whatever the elevation of the saine may be,as set forth.

ln testimony that I claim the foregoing I have hereunto set my hand andseal this 24th day of February, 1875.
